` j UNITE Thisinvention relates to a new and use- .ful device in the nature of adouble-acting lrifle especially adapted for use as a weapon lof warfare,- game hunting, target practice yand the like, embodying a means of rapidly firing a number of bullets by the operation -or ypulling of the trigger of the rifle.

object of the invention is to provide a z' double-acting riflev of new and novel conystruction.embodying certain adjustable feai tures hereinafter more fully v described, claimedand lillustrated'in the accompanying t dwing, Y ufFig: 1 is a side elevational View of my improved rifle. p l Y Fig. 2" is an enlargedfragmentary longivtudinalcen'tralsectional view thereof. 3 is Va detail fragmentary central secl#tional view showing in particular the cartridge feed mechanism'. Y n Y Fig. Lisis, a horizontal sectional view taken onthe line 4 4' of Fig. 3. Y p IFig. 5 is a Similar sectional view taken on thesline 545 of Fig. 3. `Fig. 6 is :afront elevational view of the cartridge holder as embodied in my improved automatic rifle. y. Y As hereembodiedmy improved rifle com- 'f y prises-briefly a stock 10 of usual rie or gun y construction adapted to permit my improved' f rifle to be held to the shoulder of the person j` usngsame p vrThemain portion comprises an upper member 11 andlower member 12, attached. or secured to each or by the threaded members 13, '-bolts, screwsstuds or the like. The lower y14e, similar to the above described threaded 'members 13. The upper member 11 has formed therein an aperture adapted to re- 'oeive'the rearportion 15 of the rifle ybarrel 16 Whichextends therefrom and which is of j the usual tubular construction, and whichis rigidly secured to the said upper member 11. l Apg-rip member 17 is secured to the under upper memberrll by the clip 18, and extends viding: a suitable grip or support for the .hand of the person using my improved riiie, asis generally the practice in the us-e of rifles 'or guns.

' The cartridge holder as embodied in my improved rifle comprises a band member 19 fof'flat ring like construction having secured #thereto at its` outer periphery a plurality of AND;v BOCHNAK, OF BOBTOWN, PENNSYLVANIA.

. memberf12 issecured to the forward extre`m' j ity of theV stock 10 by the threaded members therefrom directly under the barrel 16, nro-V :DOUBLE-ACTING RIFLE.

tubular members 20 adapted' to slidably `receive the cartridges 21.V The said cartridges are of the usual rifle or gun type and are pro- Vided with the usual bullets 22, which project in the usual well known'manner for the forward extremity of the cartridges, and

Y which are also provided with the usual enH` cured to the pin 28 rotatively mounted in the lower member 12, by means of thelock pin 29, or in any suitable manner. The spool 26 has formed therein a plurality ofelongated notches 27, radially formed therein adaptedv to engage or receive the projections 24.

The hammer 3() is pivotally mounted on the pin 31 carried in the lower member 32, and f is of the usualriiie or guntypeand has secured thereto a tension spring 32, which is also secured to the pin 3.3carried in the lower member 12, as a means of normally holding the hammer 30 in a locked position ready for firing.

The triggerl 34; is pivotally mounted intermediately onthe pin 35 y carried in the lower member 12 and is provided with a free extremity 36, adapted to engage the extended element 37 vof the above mentioned hammer y30. The trigger 34; extends somewhat below the lower portion 12 and is protected against accidental operation, by means of the usual trigger guard 38, secured as at 39v to thellower member 12 and extended therefrom.

The firing pin 40 is slidably mounted in the opening formed intermediatethe upper and 10o n l lower members 11 and 12, and is normally held in a disengaged position with the enlarged head 23 of the said cartridge 21 by means of an expansion spring 41, coaxially positioned thereon, and which engages the enlarged portion 42 of the said firing pin, for thepurpose as above set forth. A threaded member 43, being secured to the said upper and lower members 11 and 12, and having.. formed therein an axial openingthrough which the said firing pin 40 extends some- I what. The firing pin 40 is provided with an enlarged head 44which is provided with a Y suitable extremityY to accommodate oriire either center or rim fire cart-ridges.l Y Y f The above described construction is such as will permit the said hammer 30, which'forced forward designated by the reference'numeral 45, by the pulling of the trigger 34, designated by the reference numeral 46,7cause the said hammer to strike theextendedl extremity of the firing pin 40, urging the said firing pin 40 forward and causing the enlarged extremity 44 of the said firing pin to strike the cartridge 21, `exploding the cartridge and eX-y elling or shooting the bullet 22 througliY the arrel 16.

VA pin 47 of squaretransverse sectionvis slidably mounted in the lower member 12 andis normally held in anextendedposition by means of an expansion spring 48. Y The pin 47 is provided with a projection 49 adapted to engage in a notch 50 formed in the; disc l secured to the pin 52 rotatively'mounted in the lower member 12. A bevel pinion 53 is secured intermediately to the pin 52 and vmeshes withv a similar pinion 54V secured to the above mentionedpin 28, or teeth may he .formed in the extremity of the-said pin 28. g The above Vdescribed construction is such as will permit the hammer when operated by t-he't'rgger 34 as above set forth to strike the Y extended extremity of the pin 47 as a means of partially rotating the spool 26 for the pur- Cir pose of partially rotating the cartridgc'holder which will positionY theV cartridge placed Ytherein next to the Acartridge which has been fired inl alignment with the barrel 16.

Having thus described my invention what Il claim yas new and'desire to 'secure by United States Letters Patent is :a
